We have made the first direct measurement of the parity-violating coupling of the Z^0 boson to the strange quark, A_s, using ~550,000 e^+e^- ->Z^0->hadrons events produced with a polarized electron beam and recorded by the SLD experiment. Z^0 -> s-sbar events were tagged by the absence of B or D hadrons and the presence in each hemisphere of a high-momentum K^+- or K^0_s. From the polar angle distributions of the strangeness-signed thrust axis, we obtained A_s=0.895+-0.066(stat.)+-0.062(syst.). The analyzing power and u-ubar plus d-dbar background were constrained using the data.

Probing New Physics with the Electron Yukawa coupling
Simplified models that can chirally enhance the electron Yukawa coupling are classified, and their reach at FCC-ee and via (g-2)_e is quantified, showing (g-2)_e is often competitive but not always.

The Higgs boson through the lens of electroweak precision data
Updated Gfitter EW fit with new MW average yields SM-consistent indirect observables and, via kappa_V from oblique parameters plus LHC signal strengths, determines Gamma_H to ~10% precision under leading-log assumptions.
